AXLE-TRUING MACHINE.

Application led July 23, 1921, Serial No. 487,016.

To all whom tmag/ conce/m. i l a frame consisting of an arched bar 1 adapt- 55 Be it known that I, THOMAS J. HADDEN, ed to extend over the axle and the wheels a citizen of the United States, residing at thereon` as shown in Fig. 1, and having Mount Carmel, in the county of Wabash one end supported upon caster wheels 2.

and State of Illinois, have invented certain The opposite end of the frame is formed new and useful Improvements in AXleinto a split sleeve 3 having depending lugs 60 Truing Machines, of which the following 1s or ears 4 through which a clamping screw a specification. Aor bolt 5 is inserted. This clamping screw This invention relates to machines for or bolt, as shown most clearly in Fig. 6, is

truing car journals without removing the loosely fitted through one of the lugs 4:

wheels and has for its object the provision ot' and has threaded engagement with the oppo- 65 an apparatus which may be easily and quiclrsite lug whereby, when the bolt or screw ly brought into position to operate upon the 1s rotated in one direction, the lugs will be journal and accurately centered therewith. caused to approach each other and when the A further object of the invention is to proscrew or bolt is rotated in the opposite diw vide means whereby the cutter or other tool rection they7 will be permitted to spread 70 may be easily and quickly adjusted to clear apart. Extending longitudinally through the Bange of the journaland brought into this split sleeve 3 is a hollow centering shaft position to operate upon the journal, and or barrel 6 provided upon its upperportion a still further object of the invention is at its inner end, with a rack 7 with which -to provi-.lel simple and. compact mecha meshes a pinion 8 housed within the split 75 nism whereby the tool will be caused sleeve above the rack, as clearly shown. This to travel longitudinally of the journal while pinion 8 is carried by a transverse spindle 9 acting thereon so that all parts of the jourhaving one end extending through 'the side nal will be accurately finished. Another obof the sleeve and constructed with an anject of the invention is to provide simple gular terminal to be engaged by an operat- 80 means whereby the tool may be easily seing han-file 10. At its outer end the barrel 6 cured in working position upon its carrier, has its bore internally threaded, as shown and other objects of the invention will ap at 1l, to b'e engaged by the eXteriorly thread pear incidentally inthe course ofthe followed portion 12 of a centering pin 13 which ing description. The invention resides in extends longitudinally through the barrel 85 certain novel features which will be particand is adapted at its inner end to engage the ularly pointed out in the claims following center of the adjacent car journal. The outthe description er e'\t1em1ty ofthe pin 12 is angular in cross In the accompanying drawings which ilsection to be engaged by the operatin lustrate one embodiment ofthe invention,- handle l0 When the centering pin is to be 90 Figure 1 is a Side elevation 0f the appaforced into supporting engagement with the ratus in position to act upon a car journal; journal. It will be readily understood from Fig. 2 is an enlarged longitudinal section the drawings that the machine is arranged 40 0f the machine; to operate upon the journal 14 at that end Fig. 3 is a transverse section on the line of the frame remote from the centering pin 95 3-3 of Fig. 2; and the journal 15 adjacent the center- Fig. 4 is a detail perspective view of the ing pin 13 is utilized during the truing opmeans for securing the tool in place; eration as a partial support for the frame.

Fig. 5 -is an enlarged plan view of the The working end ot' the machine carries i support for the-tool-carryiug arm; a centering pin 16 which is engaged in the 00 Fig. 6 is a detail Section on the Mn@ 6-6 center upon the journal to be trued, after of Fig, 2; which the supporting end of the frame is Fig. 7 is a detail perspectiveview of one brought down into position beyond but adof the wedges for adjusting the tool-carryjacent the journal l5 and the handle 10 is ing arm. engaged upon the cnd of the spindle 9 and 105 Fig. 8 is a detail of the means for rolling ..uauipulated to cause the barrel 6 to apand polishing the trued, journal. proach the said journal, the centering pin 13 ln carrying out my invention, I employ being thus brought into engagement with the center on said journal. The handle 10 is then engaged upon the adjusting screw or bolt 5 and manipulated to clamp the sleeve around the barrel (S so that movement of the barrel will bc prevented, after which the handle is engaged upon the outer extremity of the centering pin and turned so that the pin will be forced into binding engagement with the journal and the machine thus brought into accurate axial alineineiit with the journal which is to be trimmed. It will also be noted that the operator assumes a position adjacent that end of the machine carrying the tools and which is disposefl adjacent the journal 14, while a helpenadjusts the supporting end ot the frame into proper relation to and in engagement with the remote journal 15. After one journal has been treated, the machine may be released by reverse manipulation of the centering pins and then shifted parallel with the track 17 so as to operate upon another journal at the same side of the track 17.

As shown most clearly in Fig. 2, the easters 2 are swivelly connected with the extremity of the frame bar at the. working end ol the same and immediately above said extremity an opening 18 is formed through the said bar to receive the outer end of a tubular body 19, the centering pin 16 being disposed at the inner end of said body at the center of the same, as shown. This tubular cylindrical body 19 is provided with an annular flange 2O which is adapted to bear against the inner face of the frame bar and upon the outer extremity of the said body is fitted a nut or ring 21 which is turned home against the outer face of the frame bar so that the body will be firmly secured in the frame. Disposed longitudinally Within the cylindrical body 19 and at the axis of the same is a rod Q2 which has smooth end portions but within the bore ofA the body is constructed with coarse threads 23 and a nut or threaded sleeve 2lis mounted upon this threaded portion of the rod 22 and constructed with a finger 25 projecting through a longitudinal slot 26 inthe body, as shown clearly in Fig. 2. Upon reference to said Fig. 2, it will be noted that the bore of the cylinder lor cylindrical body 19 is open at its rear or outer end and the rod 22 extends through said end and is supported by a. nut 27 threaded into the end of the bore and bearing against an abutment 28 formed on the rod so that the rod will be swiveled in the cylinder but will be held against endwise movement in one direction, endwise movement in the opposite direction being prevented by the inner end of the threads 23 and by gearing upon the outer end ot the rod which will be hereinafter described. Loosely iitted upon the cylinder at the inner side of the 'frame bar is a. sleeve or traveler 29 provided at its outer end with an annular recess 30 receiving the finger 25, and upon the. outer end ot' the said traveler l secure a cap plate 3l which extends over the said .recess 30 and thereby retains the finger 25 iii engagement therewith. lt will thus be seen that the traveler may rotate about the cylinder and also slide longitudinally thereupon and longitudinal movement will be inipaited to the traveler b v thel finger 25 which must follow the endwise movement of the nut 24 but is prevented i'roin rotating by the sides of the slot 26. The traveler Q9 is provided with spaced ears or ribs 32 at diamctrically opposite points and the toolcairying arms 33 are provided near their outer' ends with lugs 34 adapted to fit between the said ribs or ears and be attached thereto by pivot pins 35 inserted through registering openings in the said lugs and in thc ribs 32. The ribs 32 also serve as bear ings for the .smooth ends of screws 36 pi'ovided at the opposite sides ot the. pivots and equipped at one side of the machine with angular terminals 3T which may be engaged by a convenient turning1 handle. The ,threads upon these screws are revcrsely arranged, as shown most clearly in Fig. 5, and the terminals 3T of all the screws are disposed at the saine side of the machine so that the operator will not be under the necessity of shitting from one side of the niachine to the other side when adjusting the tool-carrying arms. The arrangement also removes the uncertainty as to the direction .in which the screws must be turned to attain a desired result inasmuch as both the screws will be turned in one direction to bring the tool-carrying arm into operative position and turned in the opposite direc-- tion to bring the tool-carrying arm into its inoperative position. The tool-carrying arm is provided in its edge or side presented to the traveler with transverse grooves or reees-scs- 38 in which are engaged the adjusting slides or wedges 39, the said wedges having their inner edges concaved transversely, as shown at 40, and provided with transverse threads 41 which are adapted to engage the threads of the adjusting screws A3G whereby rotation of the screws will et- `fect endwise movement of the said slides or wedges. Obviously, it these wedges be caused to move toward one side of the machine, the tool-carrying arm 33 engaged thereby will be caused to rock upon`its pivot 35 so that the inner end of the same will move radially outward from the cylinder 19 and if the wedges be caused to move toward the opposite side of the machine, a reverse movement will be imparted to the tool-carrying arm.. It will also be understood that the Wedges engaging one toolcarrying arm are arranged reversely to each other, that is to say, the smaller end of one wedge is arranged attlie same side of the wedges apparatus as the larger end of the cooperating wedge inasmuch as the tendency of the must be to move the engaged portions of the arm in opposite directions as the wedges are disposed at opposite side of the pivot of the arm.

For the purposes of illustration, I have shown two tool-carrying arms, but it is to be understood that a greater number of arms may be employed -if so desired, although ordinarily two arms will be found suflicient. One of the arms is shown as carrying a cutter 140, while the other arm carries a roller 141. The cutter 140 is inserted through a longitudinal slot in the stem or shank 42 which is tapered to engage a tapered socket 43 in the end of the arm 33. The stem is provided near its smaller extremity with a longitudinally disposed slot and a wedge-shaped key 44 is inserted through registering openings in the arm and the said slot so as to draw the stem firmly into the socket and thereby support the tool so that it will be held firmly to its work. A. spacing collar 45 is the stem between the cutter and the end of the arm 33 and the cutter may be further secured against said spacing collar by a washer 46 and nut 47 mounted upon the outer extremity of the'stem. The roller 141 is mounted upon the carrying arm 33 in a similar roller need not be provided with a longitudinal slot near its outer end, a smooth portion 49 of circular cross section being utilized as a bearing for the roller and the roller being retained thereon by a washer 50 and a nut 51 similar to the washer 46 and nut 47. A spacing collar or ring 45 is, however, employed between the end of the arm 33 and the roller and a key 44 is inserted through registering openings 52 in the arm and the slot 53 in the stem 48. This means for mounting the tool upon the arm 33 will effectually retain the tool in position while it is at work but permits its ready detachment when anew tool is to'be substituted or the tool which has been in use is to be sharpened or otherwise repaired.

Upon the traveler 29 at the outer end thereof. I secure a gear wheel 54, preferably by a key 55, and this gear 54 is in mesh with a gear 56 upon the driving shaft 57, the

.gear 56 being provided with circumferential flanges 58 engaging the radial faces of the gear 54 so that` when the gear 54 moves longitudinally with the traveler, the gear 56 will be likewise moved. The driving gear 56 is mounted upon the driving shaft 57 so that, while it is constrained to rotate with said shaft, it is free to travel longitudinally of the same and the said shaft is journaled in the depending end of the frame bar and in a bearing hanger 59 formed on the said frame bar. The shaft 57 extends outwardly preferably fitted upon manner, but the'stem 48 carrying the beyond the frame bar and through a gea-r casing 60 which is secured upon the outer side of said bar. I have shown the outer end 61 of the driving shaft as or other turning tool` but it is to be understood that power may be applied to the shaft from any convenient source such as an electric motor, a compressed air engine, or any other prime motor. Within the gear casing 60, a spur pinion 62 is secured upon the driving shaft and Said pinion meshes with a combined spur and beveled gear 63 mounted upon a stud 64 upon the frame bar below the driving shaft. The beveled face of this gear 63 meshes with a beveled gear 65 on the upper end of a vertical shaft 66 which is mounted in a projection 67 on the gear case and upon the lower end of said shaft 66 is a beveled gear 63 which meshes with a beveled gear 69 upon the feeding rod or bar 22. It will be noted that the gear 68 is at the inner side of the gear 69 so that it resists inward movement of the gear 69 and, consequently, aids in preventing inward endwise movement of the feeding bar 22. ,The outer end of the said feeding bar or rod is shown as equipped with a crank handle 70.

At its inner end, each arm 33 is provided with a lug 71 having a seat or socket 72 to receive one terminal 73 of a clamp bar 74- or the end of a screw 75 mounted in the terminal 76 of said bar.

The operation of the machine will` it is thought, be readily understood. lVhile the machine is being brought into working position, the arms 33 are disposed in' positions relatively remote from the cylinder or main body 19 so that they will kclear the flange at the outer end of the journal. The centering pin 16 is engaged in the center ofthe journal upon which work is to be done and the pin 13 is then engaged with the remote journalLas previously set forth. The adjusting screws 36 are then manipulated so thatI the cutter 140 and roller 141 will be brought to' bear upon the journal adjacent the flange thereon` after which power is applied to the driving shaft 57. The motion of the driving shaft 57 will be transmitted to the traveler 29 to rotate the same through the gears 56 and 54 and will also be transmitted through the train of gearing hereinbefore described to the feeding bar or rod 22 to effect rotation of said bar. The rotation of the traveler will. of course, carry the arm 33 around the cylinder 19 concentric therewith andthe cutter 140 and the roller 141 will be caused to travel likewise around the journal 14, the cutter removing any projecting portions of the surface of the journal so that it will be reduced to a true cylinder., and the roller serving as a support for the journal to prevent its bending under the of angular cross' section so that 1t may be engaged by a crank force exerted thereon by the cutter and also serving to compress any splmters or other slight imperfections left uponthe surface by the cutter.l The rotation of the feeding bar22 will act upon the nut 24 so that it will be caused to travel longitudinally of the feeding bar or rod and the engagement of the finger 25 with the traveler will, of course, impart longitudinal or endwise motion to the traveler so that the cutter and the roller will be fed from the outer end of the journal toward the inner end thereof. When the tools have traveled the entire length of the journal, the power is shut oil from the driving shaft 57 and the crank 70 is rotated to reversethe movement., of the feed bar so that the feeding nut 24 will be brought quickly to the front end of the slot 26 and the tools returned to the initial position. It will be noticed .that the stud 64 carrying the gear 63 is longer than the thickness of the ear. When a reverse rotation is imparted to the feeding bar, the gear 63 may be shifted out of engagement with the beveled gear 65 so that the motion of the feeding bar will not be transmitted to the driving shaft. lf a single operation of the tools does not sufticiently reduce the journal but leaves its surface still irregular, the cutter may be adjusted'through the stem 43 so as to further reduce the journal if it be again caused to travel thereover and if it be necessary to substitute a roller 141 having a greater diameter, the substitution can be quickly made by manipulation of the retaining washer and nut.

When the journal has been sufficiently reduced by the cutter, the cutter is removed and a roller 77, similar in all respects to the roller 141, is substituted therefor. The clamp bar 74 is then brought into position, as shown in Fig. 8, and pressure applied through the screw 75 to cause the two rollers to bear with considerable force upon the journal. Power is then applied to the driving shaft 57, as before. and the rollers will be thereby moved around and along the journal, polishing the same and making its surface smooth and even throughout.

It will be readily noted that I have provided a very compact and simply constructed machine which may be easily operated and which will prove efficient in use. rl`he makchine is suliiciently heavy to withstand the strain to which it is subjected while in operation but is not so heavy that it cannot be easily handled by two men.
